Operated Liquid-V ending Devices, of which the following is a specication.

Our Invention relates to certain improvements In that class of coin-operated vending devices which are used to deliver liquidsv in measured quantities, and is particularly adapted to the vending of a variety of liquids from a single machine.

Features of our invention relate to the employment of direct-pressure pumps which can be made separately operative by the introduction of a coin into a chute corresponding with the pump which is desired to be putinto` action, and other features relate to the means for operating said pumps, and which means comprise a rotatable shaft which is adapted to be rotated manually, and carries thereon a series of cranks adapted by the deposit of a coin in the machine to be locked in engage.

ment with a lever carried by a rock-shaft, and which lever is made to transmit-a reciprocating movement to the plunger of the pump, the shaft being locked against rotation, except when a coin is introduced, by the engagement therewith of a locking-lever which is tripped by the action of the crank-arm upon the operating-lever above described, so as to permit the4k shaft to make one complete revolution and the pump to make a complete stroke. Suitable meanssuch as springs-are employed to return the parts to their normal and operative position after they have acted, and a variety of liquids, such as perfume, may be delivered from a single machine by providing anumber of receptacles to contain the pery'fume and providing each with its pump and actuating mechanism, all of which maybe so interconnected as that by the introduction of a plurality of coins simultaneously the pumps may be made to act simultaneously for the delivery of liquids from a plurality of vessels at the same time.

In the accompanying drawings, Figure l is a front elevation of the device in the preferred form of construction, and Fig. 2 is an elevation in vertical section through the casing of the device. Fig. 3 is a plan view below the line 3 3 of Fig. l. Fig. 4 is a sectional elevation through the casing, and showing u the operating mechanism in front elevation. Fig. 5 is a sectional elevation through the casing and operating mechanism, including the valve construction, the dotted lines of said figure indicating a secondary position of the moving parts. Fig. 6 isa detail of the pump mechanism.

In the drawings, A represents a casing `to contain the fluid-receptacles B, any number of which may be used, and each of which has a cap or cover l), to which is pivoted a keylever C, having a vertically-adj ustable strik ing-head c. The key-lever is apertured about its mid-length, and through said aperture a hollow plungerD is passed, an open coiled spring d being interposed between the keylever and the top of the cover. The plunger is secured with the key-lever by a pintle or equivalent device, so as to permit a slight rocking of the lever, and the aperture will be formed so as to allow such movement. From the upper end of the hollow plunger a ilexible pipe E leads to the delivery-nozzle F. In the machine illustrated in the drawings four of these discharge-pipes are indicated which lead from as many reservoirs containing different kinds of fluid-as, for example, a variety of perfumes.

Within the reservoir and preferably upon the bottom thereof Vapump-chamber is formed, in this instance by an inverted cup G and a iiexible wall II, which forms a diaphragm upon which the plunger is made to bear, said plunger having its lower end enlarged circumferentially and rounded so as to force the iiexible wall inwardly. The diaphragm is perforated beneath theend of the hollow plunger. An inlet-aperture f is provided in the wall of the cup, which has also an aperture in its bottom, and to which aperture is adapted a gravity-valve f, arranged so as to seal the aperture during the working stroke of the pump, as shown in Fig. o.

The pumps are operated by mechanism which is particularly illustrated in Figs. 3, Ll, and 5 of the drawings. Said mechanism comprises a frame K, secured within the casing and having journaled at the upper frontcorner thereof a rotatable shaft L, bearing thereon a gear M, enmeshed with a similar gear N, carried upon a stub-shaft, which has a bearing in the easing and carries on its end outside the casing a crank by which the shaft may be rotated. A ratchet and pawl prevent the turning` of the shaft in one direction.

Upon the shaft L are a series of arms or cranks L', secured to rotate with the shaft'. The latter is locked against operative rotation by the engagement of a locking-stud a on the gear-wheel M with a locking lever or trigger O pivoted between its ends on a second roek-shaft I, which is journaled at the rear upper corner of frame K. The rockshaft l carries a number of skeleton bcllcranks P, corresponding to the number of pumps employed, the front end of these bellcranks being flattened to provide a coin-re eeptaele and having in the flattened portion a slit p, above which the projecting ends of the arms or cranks 011 the shaft L project and through which slits said arms are adapted to pass duringthe action of the parts. Therear ends of the bell-cranks are normally depressed by a spring-controlled rod Q, which may be made integral with rock-shaft l or carried in arms s ecured therewith. Spring r] is secured to one member of the bent level' R, pivoted on the side of the frame K,a11d having its front end projected into engagey ment with a stop or lug Z on the shaft L. The action of this spring and rod is to hold the rear ends of the bell-cranks down and their flattened front ends up to a position slightly below the projecting ends of the operating levers or cranks and permitting a coin which may be delivered into the upper end of the coinchutcs T to come to rest on the flattened ends of the bell-cranks and covering the slots therein and in position to be engaged by the projecting cranks or arms when the shaft L is rotated. The bell-cranks are normally in engagement with sliding rods U, said rods being for convenience of construction bent to provide two downwardly-projeeting legs, one of which enters an aperture in the frame, and is normally held in contact with the lowerside of the bell-crank lever by an open coiled spring surrounding said leg, while the opposite leg projects into the chamber below and is adapted to impinge upon the striking head of the key-lever and when depressed to cause a downward movement of the pump-plunger.

In operation, when a coin is deposited in one of the coin-chutes, it slides down the latter and comes to rest on the flattened and slitted end of the bell-crank lever before described and beneath the projecting ends of the arm or crank of the rotating shaft. lf now power be applied the cranks or arms will be brought into engagement with the coin and by means thereof locked in operative condition with the bellcrank lever, thus depressing the forward ends of the latter and rocking the shaft on which they are mounted in its bearing. A slight rotary movement is permitted to the shaft L after it is locked to the bellcrank lever, sufficient to rock the shaft I in order to depress the f ront end of the trigger, and thereby remove its engaging end from the path of the stud n. on the gear M, and which is thus made free to complete one revolution. During said revolution the bell-crank, which has been made operative by the insertion of a com, has depressed the sliding rod and through 1t the pump-plunger, collapsing the diaphragm and expelling the liquid contained in the chamber beneath it through the hollow of the plunger and through the flexible pipe, de livering it at the nozzle. During the revolution ofthe shaft the coin will be dragged oft' the bell'crank lever by the arms or cranks on the rotating shaft and will drop down'withln the casing of the machine, thus leaving the apparatus locked against operation except by the insertion of another coin. After each working movement of the trigger and sliding rods they are returned to their normal positions by their respective springs.

It is apparent that each of the jumps may be worked independently or that any two or more may be worked simultaneously by the insertion of coins in the respective chutes, and thereby a variety of perfumes may be dclivered simultaneously from a single machine, or two or more sorts of perfume may be delivercd simultaneously through the nozzle, thus effecting a combination of the perfumes.

It is obvious that Variations may be made in the structural features above described without departing from the spirit of our invention, and that some of the features may be used in a machine where others are not used.
